When a dam is built, several environmental changes can occur. Here are the answers to your questions:
1. Water Temperature Changes: Dams can alter the temperature of water in a river. The water released from the bottom of a reservoir is often cooler than the water upstream, which can affect local ecosystems and species that are sensitive to temperature changes.
2. Site Stability for Support: It’s critical to ensure that the site is stable enough to support a dam because an unstable foundation could lead to structural failure, flooding, and significant environmental damage. Engineers typically conduct geological assessments to evaluate soil, rock formations, and water levels.
3. Fewer Trees Around Reservoirs: Fewer trees may grow around a reservoir because the flooding of the area can submerge existing vegetation or because the altered water levels and changes to soil moisture can make it less suitable for tree growth.
4. Water Storage During Drought: A dam can store large amounts of water, which can be used to supply water during drought periods. The capacity varies with the size of the dam and reservoir, but important calculations are made to determine how much water can be held based on rainfall patterns and water demand.
